Did you know, you can still access recent national C0VID #wastewater data in the U.S.?

I'll walk you though it.

🧵
1/ Verily national wastewater graph
First, go to Verily's #wastewater website.


Click on the little Line Graph icon on the left side.

2/ data.wastewaterscan.org
Click the line graph icon
When you click on the Line Graph icon, it makes an annoying pop-up.

In the 1st menu, choose SARS-CoV-2.

In the 2nd menu, click *ANY* location. We want national, but they don't include it there. So pick anywhere, and we'll fix it later.

3/ Useless pop-up window
Click the "Get Started" button. Then you'll see something like this. It's the recent wastewater data at whatever rando site you selected.

Again, this is not what we want yet.

4/ Recent wastewater data at one rando site
Now, click to the right of the magnifying glass by "Location(s)" --> then "National" --> then "All Wastewater Sites"

5/ Location pop-up menu
The graph that will come up is overwhelming. No data synthesis. We're getting closer though.

Click the little crossed out eyeball I've circled in red.

6/ Graph of all wastewater data. No national average.
Woo-hoo. We finally have a national average line. I can see why the CDC prefers this over Biobot. 🤣

Click a number on the vertical access and drag up or down (it moves opposite of how I expect). Play around with the start date too. See red circles.

7/ Verily data with national average.
I like to see either the entire pandemic (big picture) or the last 6-7 months (current wave, shown).

8/ Data focused on the current wave
If you zoom out to see the entire pandemic, you'll find a similar picture relative to what you may have been tracking with Biobot, Walgreens, etc.

The waves show up. The estimates of magnitude vary by methodology.

9/

I hope to post an interim Biobot-to-Verily PMC forecast Monday.

I stand by prior forecasts. We'll reach the bottom of the current (very high) valley in 1-2 wks. Cases will pick up noticeably so around mid-November and get very very bad in Dec/Jan.

10/
Point of clarification: Verily data are included in this dashboard, but others have noted Verily does not own the dashboard. The language on their website is ambiguous in this regard, IMO (pic below). It's the first link on Verily's page.

Others report that as CDC Biobot sites come on, they will be included in a Verily-specific dashboard, independent of that above. It seems that rather than harmonizing and unifying data, we are at risk of proliferating more and potentially lower quality dashboards.

11/
Verily's web page begins by linking to a comprehensive dashboard that they reportedly do not own. Their own limited dashboard follows below on the page.

The transmission forecast suggests 300-500k daily infections the next month. If the data get retroactively corrected downward, we could dip to 200k.

PMC Update on #ExcessDeaths

🔥109,000-175,000 people in the U.S. are expected to die as a result of COVID in 2025, based on estimates derived from Swiss Re
🔥COVID deaths expected to be on par with lung cancer in the U.S. in 2025
🔥Death data added to the dashboard
2) Full video links to learn more about COVID #ExcessDeaths in the U.S.

Veed platform: veed.io/view/558039f4-…
3) The new #ExcessDeath statistics build on what we described in the 5-year pandemic anniversary video.

Watch from 12:14-20:00 to see how simplistic models underestimate COVID deaths. The Swiss Re model solves that problem. PMC extends that work.

We have had a steady state of about a half million infections the past several weeks. That's over 50 million estimated infections so far in 2025.

There's a good chance of steady transmission the next month. Often, we'd head into a low lull about now. BUT there are no universal precautions, immunity is waning from the fall & winter 2023-24, & viral evolution looks less 'lucky.'Middle forecast shows 400-600k daily infections.

1) 5-yr Anniversary of the WHO Pandemic Declaration

🔥10 waves
🔥Covid mortality rivals lung cancer
🔥8 infections/person by 2030
🔥Long Covid as catastrophic
🔥Death trajectories becoming complex
🔥"During Covid" as anti-science rhetoric
🔥Serious ppl take Covid seriously
🧵
2) Wastewater-derived estimates of case rates show international consensus 20-26% of populations got Covid during the peak 2 months of the 2023-24 winter wave in the U.S., Canada, and the U.K.
3) The ratio of reported cases versus true cases has remained consistent, demonstrating the validity of wastewater-derived estimates. True cases are 15-30x reported cases, a consistent ratio. There are no examples demonstrating low case rates.

1) Mardi Gras 2020 was 5 years ago today. ⚜️

It was before the pandemic declaration, before the federal government recommended masking.

COVlD spread quickly through New Orleans, leading to one of the highest mortality rates per capita in the U.S.... Timeline showing Mardi Gras 2020 just 4 days before the first known reported death of C19 in the U.S.  Note. "Peak" diagnoses refers to the peak of the 1st wave.
2) New Orleans service workers were disproportionately hit by the early pandemic. Many died. Many developed #LongCOVID at the time or have now through repeat infections. Many have switched to other sectors....

3) The sad fact is that many service workers are continuing to get #LongCOVID through repeat infections today because the pandemic is ongoing and many restaurants have high occupant density and horrendous air quality....

This is a mid-sized wave, meaning substantial transmission. Notice that transmission remains steady at high rates.

Expect steady or slightly declining transmission, unless the real-time data are retroactively corrected.Two graphs, showing year-over-year transmission and the forecast, summarized in the post.
3) PMC COVlD Dashboard, Feb 17, 2025 (U.S.)

Notice that 30 states remain in high/very high transmission, per CDC categories.

This is the same as last week. Transmission is 3x higher than in Feb 2021, when people were taking more precautions around masking and testing.Transmission heat map and CDC line graph of regional variation in transmission.
